Title: Aromatic polyamide film and solar cell using it
Inventor: ITO NOBUAKI
IPC: B29C55/14
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To reduce surface faults with a flat surface of an aromatic polyamide film by forming the film having a specific heat shrinkage factor and slack amount, thereby utilizing high rigidity and heat resistance. SOLUTION: The aromatic polyamide film has 21 or less of a heat shrinkage factor in a width direction at 210 deg.C. If the factor is less than 28, the film is deformed by a heat in the case of attaching an amorphous silicon thin film, and hence a good film is not obtained. A slack amount of the film at a center is 60 mm in the case of applying a load of 0.5 kg/mm<2> to the film having a width of 610 mm and a length of 2 m. If the slack amount is less than 60 mm, the film is released from a support on the support such as a drum in the case of providing the silicon thin film, the film is deformed by the head or a contact with a guide roll is deteriorated at the time of feeding the film, and hence there occurs a problem in which a damage is formed on the film. The solar cell having the silicon thin film on the polyamide film is flat and has excellent film characteristics.

Abstract: PROBLEM TO BE SOLVED: To provide a push-in flaw prevention method for a hot roll steel band by which an elimination of deposited elements on a steel plate surface can be performed more perfectly and, an elimination of a side face push-in flaw can be performed as well, while a pair of left and right pinch roll front nozzles installed between a conventional side guide and pinch rolls alone are insufficient for this purpose. SOLUTION: When a hot rolling steel band 5 is produced, a high pressure water is sprayed from a pair of left and right pinch roll front nozzles 3 installed between a pair of left and right side guides 1 and pinch rolls 2 at an inlet side of a winder 10. In addition, a high pressured water or a high pressured air is sprayed from side guide upper nozzles 4 installed respectively at an upper end of the side guides 1 towards a clearance 8 between the side guide 1 and a pre-guide 6 at its upper stream so as to eliminate and prevent a deposit 9 being stuck to an edge surface of the steel band 5.

Title: Pulse applicator
Inventor: OKAMURA CHIYUUJI
IPC: H02M7/48
Filed: 1978-04-26
Abstract: PURPOSE: To improve the efficiency of survey, by enabling the constant application of prescribed pulses even if the resistance of a load varies.  
     CONSTITUTION: A voltage Vd produced by dividing the terminal voltage of a power capacitor 12 through resistors 21, 22 is compared with a reference voltage e by a comparator 23, which generates a trigger pulse VT when the voltage Vd has exceeded the reference voltage e. If the voltage Vd has exceeded the reference voltage e in charging, the comparator 23 produces a trigger pulse VP. When the charging voltage has a prescribed level VC, a vacuum switch 13 is actuated so that the voltage of the high-voltage pulse Vp which is the output of the switch becomes constant despite the magnitude of the grounding resistance on a trouble point.  Therefore, the prescribed pulses can be always applied to the load even if the  resistance of the load varies.

Title: Method of controlling idling revolution speed of internal-combustion engine
Inventor: SASAKI SHIGERU
IPC: F02D31/00
Filed: 1983-03-24
Abstract: PURPOSE:To improve a drivability, by effecting feedback control when the speed of a vehicle is higher than a low set value and the transmission of the driving power of an engine is cut off during the entire closure of a throttle valve. CONSTITUTION:When it is judged in a step 100 that the speed of a vehicle has exceeded a low set value, a transfer is made to a step 106. When the transmission of the driving power of an engine is cut off, a transfer is made to a step 102. When it is judged in the step 102 than a throttle valve is entirely closed, a transfer is made to a step 102. When it is judged in the step 102 that a throttle valve is entirely closed, a transfer is made to a step 104 in which feed-back control is performed through the quantity of air sucked into a by-pass and the quantity of fuel, to keep the rotational frequency of the engine at an aimed value. The drivability of the vehicle is thus improved.

Abstract: PURPOSE: To prevent the drop-out defect and mispositioning by adhesion of foreign matter by adhering a transfer sheet and a member to be transferred right after dropping of a non-solvent type adhesive and forming the parts where light shielding films and color filter overlap as spacers. CONSTITUTION: The color filters 3 of plural colors are formed to prescribed pattern shapes by a pigment dispersion method, etc., on a transfer base 1 consisting of, for example, a metallic sheet. The light shielding films 4 consisting of resins dispersed with black pigments are so formed in the spacings between the color filters 3 in such a manner that the peripheral parts thereof have overlaps with the edges of the color filters 3. The non-solvent type adhesive 5 in a liquid form consisting essentially of, for example, acryl, is dropped onto the surface formed with the color filters 3 and a transparent glass substrate (member to be transferred) 6 is put thereon from above and both are press bonded, by which the adhesive 5 is uniformly spread at ordinary temp.  At this time, the projecting parts A generated by the overlaps of the light shielding films 4 and the color filters 3 act as the spacers and an adhesive layer having a uniform film thickness is formed. The transfer base 1 is peeled after this adhesive layer is cured by UV rays.

Title: Die casting method
Inventor: MURAI TAKESHI
IPC: B22C9/06
Filed: 1986-03-07
Abstract: PURPOSE:To permit easy mounting and holding of a core and sure venting of gas by maintaining a communicating path with the atm. formed in the core print part of the cavity parts in a die in a negative pressure state, mounting the core to the core print and removing the gas generated during pouring from the communicating path. CONSTITUTION:The air in the communicating path 9 is sucked by driving of a suction device and the core 7 is mounted to the core print 3g of the fixed die 3 while the fixed die 3 and the moving die 5 are held separated from each other. The negative pressure is, therefore, maintained in the communicating path 9 and the core 7 is held by the core print 3g. Both dies 3, 5 are then mated and are united to one body by clamping means. A molten metal is poured into the cavity parts 3b, 5b. Since the negative pressure state is maintained in the communicating path 9, the gas generated during pouring is sucked through the core 7 into the communicating path 9 and is discharged to the outside of the die 1. The molten metal is thereby spread to all the corners in the cavity parts 3b, 5b and the generation of casting defects is surely prevented.
